Yokohama tests AI to gauge air pressure by sound
The Yokohama Rubber Co., Ltd., has begun practical testing of a technology that uses artificial intelligence (AI) to gauge air pressure from the sound made by tapping truck and bus tires. Using AI to gauge tire air pressure from the sound made by tapping the tire, which previously relied on the driver’s experience, will provide logistics companies with solutions to various issues, including safe vehicle operation via improved air-pressure measurement, cost reductions and greater operational efficiency through labor-saving, and raising fuel efficiency by appropriately managing tire air pressure.
